SPEGIFIGATION forming part of Letters Patent No. 767,639, dated August 16, 1904,

Application filed January 21, 1904. Serial F0. 190,054. (No model.)

Dressing Machines, of which the following is a specification.

This invention relates to a device adapted for a thread-dressing machine, and has for its object to provide a device for immersing the thread in the liquid dye contained in the sizing-box and at the same time afford means for readily applying a thread to said device Without the hands of the operator becoming soiled with the dye-color.

The invention consists of the novel construction and combination of parts, as hereinafter described, and specifically set forth in the claims.

In the accompanying sheet of drawings, Figure 1 is a transverse sectional View of a trough or sizing-box and also illustrating in side elevation the position of my device therein, together with the directed feeding movement of the thread as it comes from the spool to receive the dye-color. Fig. 2 is an enlarged top plan view, partly in section and partly in elevation, taken on line m a: of Fig. 1,

' showing the parts embodying my improvement. Fig. 3 is an enlarged vertical sectional elevation view taken on line y 3 of Fig. 1.

Fig. 4 shows the relative position of thread when applied to the device prior to its immersion in the dye liquor.

Like letters of reference indicate like parts.

A denotes a standard or support Whose base is fixedly secured to the bottom of a trough or sizing-box which contains the liquid dye for the thread.

B is a wheel or disk revolubly mounted on a stud 0, which is fixedly secured to the standard or support A, and said wheel or disk is situated to rotate transverse of said trough or sizing-box b.

On the front side of the wheel or disk B,

each other on the wheel or disk B and each provided with a peripheral groove to direct the thread in its proper course through the liquid dye or sizing. On the same front side of the wheel or diskB is also mounted two thread-tension holders 6 6, each of which are made alike and constructed as follows: Referring to Fig. 2, f is an outwardly-projecting stud fixedly secured to the wheel or disk B and having an integral collar f to abut the surface of the same. The opposite or front end portion of the stud f is screw-threaded to receive a thumb-nut g. it It are two thin circular washers loosely mounted on the stud f and are arranged to have the thread which is to be saturated in the liquid dye pass between them, and a push-spring 2', which surrounds the stud f, is interposed between the thumb-nut g and washers it h to make frictional contact of the latter upon the thread. These thread-holders cc, constructed as described, are mounted in position diametrically opposite each other upon the wheel or disk B and situated near to its rollers or whirls, as shown in'Fig. 1.

j is a flat steel spring having one end rigidly secured in a slotted opening formed in the upper portion of the standard or support A,

by a rivet f and said spring has its opposite.

end portion arranged to bear against the rear side of the wheel or disk B to make frictional contact in holding the same in the position desired within the trough or sizing-box b.

The operation of my device is as follows: The wheel or diskB is first turned to carry uppermost a roller or whirl (Z and a threadholder 0 to the position shown in Fig. 4, after which the trough or sizing-box is filled with the liquid dye or sizing (designated by letter .9) until its level reaches near to the axis of the wheel or disk B, as seen in Fig. 1. The

thread which is to be treated by the dye liquor is designated by letter t. This thread comes from a spool u, situated in front of the trough or sizing-box, and passes through ascrew-eye o, secured in the wall thereof, as seen in Fig. 1. The thread thence passes through the liquid dye or sizing and over the roller or whirl (Z in the groove thereof to be directed between the washers of the thread-holder e, and from over the stud of said thread-holder the thread takes a course diametrically opposite and between the washers of the uppermost threadholder thence over the stud of the same to be directed to the feed-rolls (not shown) next above on the machine. The uppermost threadholder of thedevice is regulated to give greater tension upon the thread than that of the submerged or lowermost thread-holder for the purpose of having that portion of the thread taut which extends between the said uppermost thread-holder and the feed-rolls. The grooves of the rollers or whirls (Z (Z and the adjoining faces of the washers of the threadholders 6 c are in alinement with each other and parallel with the thread-eye o of the trough or sizing-box. Now if perchance the thread should break during its feeding movement from the sizing to the feed-rolls of the machine all that is necessary on the part of the operator is to tie the parted ends of the thread together and replace beneath or under the uppermost thread-holder and whirl in the position indicated by broken lines in Fig. 4. The wheel or disk Bis then turned to a half-revolution in the direction indicated by the arrow in said figure, and thus the thread is carried over said thread-holder and whirl as they immerse in the sizing. In this position the thread leads direct from the lower right-hand threadholder to the feed-rolls, and this directed course of thread is now brought forward by the hand of the operator and inserted between the washers of the uppermost or left-hand thread-holder to its normal position, as illustrated in Fig. 1.

It will be readily understood that by my construction and arrangement of parts I form a simple and compact device, so that a large number of such devices may be mounted consecutively in the sizing-box, and, furthermore, the operator is enabled to quickly apply a thread in position without having his fingers soiled by contact with the liquid dye contained in the trough.

This invention is an improvement upon the thread-dressin g machine shown and described in Letters Patent of the United States No. 702,786, issued to me June 17, 1902.

What I claim, and desire to secure by Letters Patent, is

1. In a thread dressing machine having thread feed rolls mounted thereon, and a trough containing a liquid sizing situated beneath the feed-rolls and provided with threadeyes in the front wall of said trough, the combination, of a device comprising a fixed standard secured in position upon the bottom of said trough; a wheel or disk mounted on said standard in a vertical position thereon and revoluble transverse of said trough; two whirls rotatably mounted on the front side of said wheel or disk, and situated opposite of each other on the same, and each of said whirls provided with a circular groove for directing the thread from the thread-eye of the trough to its proper course through the liquid sizing; two tension thread-holders mounted on the front side of said wheel or disk, close to said whirls, and each of said thread-holders arranged to make frictional contact upon the thread during its feeding movement from between said wheel or disk to the feed-rolls of 1 the machine; and a flat springhaving one end rigid in said standard and its opposite or free end adapted to bear against the rear side of said wheel or disk, to hold the latter in the position desired within the trough, substantially as set forth.

2. In a thread dressing machine having thread feed rolls mounted thereon and a trough containing a liquid sizing situated beneath the feed-rolls, and said trough provided with thread-eyes in its front wall thereof, the combination, of a standard fixedly secured to the bottom of the trough; a wheel or disk mounted on said standard and having four projecting studs rigid in its front side thereof, and two of said studs provided with screwthreaded portions at their outer extremities; two washers loosely mounted on each of the screw threaded studs of said wheel or disk, and said washers adapted to receive a thread between them; thumb nuts mounted on the threaded portions of the studs of said wheel or disk; push-springs surrounding the threaded studs of said wheel or disk and interposed between said thumb-nuts and said washers, to

TOO

cause the latter to make frictional contact upon the thread in holding the same taut in its course from between the feed-rolls of the machine; two rollers or whirls loosely mount- IIO holders provided with means for making a latter in position, all arranged substantially as proper tension upon a thread; two grooved shown and for the purpose specified.
